Sacrificing one visual hemifield during pediatric epilepsy surgery: Effects on visual search.

Objectives: To investigate early and late effects of planned surgically acquired homonymous hemianopias on visual search in children and adolescents.

Methods: This prospective study included five patients (5y 5 m-18y 0 m; 2 girls) with pharmaco-refractory epilepsies in whom one visual hemifield was sacrificed as part of the surgical strategy, and, as controls, seven patients (5y 11 m-18y 0 m; 6 girls) undergoing epilepsy surgeries not affecting the visual fields. Visual search was studied using the "Table Test", which is an everyday life-like visual search test.

Uncovering homonymous visual field defects in candidates for pediatric epilepsy surgery.

Objectives: Perimetry in children can be challenging due to low cooperation and short attention span. Especially during the pre-surgical work-up of children with pharmaco-refractory epilepsies, however, diagnosing homonymous visual field defects (HVFDs) can be crucial for planning surgical strategies. Here, we evaluated "campimetry" for visual field testing in children.
